You’ve seen them on your Instagram feed every few years. Those blurry, grainy, pixelated orange dots that your friends swear are "breathtaking" shots of a total lunar eclipse. Honestly, most photos of the blood moon taken on a whim with a smartphone are kind of a disaster. It's frustrating because the actual sight—the moon slipping into Earth's shadow and turning that eerie, copper-red color—is genuinely one of the most spectacular things you can see in the night sky.
Why does it turn red? It's basically a projection of every sunrise and sunset on Earth hitting the lunar surface at once. Sunlight bends through our atmosphere, filters out the blue light, and leaves only the deep reds and oranges. But capturing that specific, moody hue on a sensor is a massive technical challenge.
The Exposure Trap Everyone Falls Into
The biggest mistake people make when taking photos of the blood moon is trusting their camera's "Auto" mode. Your phone or DSLR sees a giant black sky and thinks, "Wow, it's dark in here, I better brighten everything up!"
The result? Overexposure.
The moon becomes a glowing white orb with zero detail, or worse, the camera cranks the ISO so high that the image looks like it was printed on sandpaper. During a total lunar eclipse, the moon is significantly dimmer than a full moon. You're dealing with a moving object in a low-light environment. If your shutter speed is too slow, the moon blurs because the Earth is rotating. If it's too fast, the image is pitch black.
Finding that "Goldilocks zone" is why professional astrophotographers like Andrew McCarthy or NASA’s veteran shooters spend hours prepping. They aren't just "getting lucky." They are manually wrestling with the exposure triangle—balancing aperture, shutter speed, and ISO—to keep the lunar seas (the maria) visible while maintaining that deep blood-red saturation.
Gear That Actually Matters (And It’s Not Always a $5,000 Lens)
You don't need a telescope to get a decent shot, though it certainly helps. Most people think they need a massive zoom. What you actually need is stability.
A tripod is non-negotiable. Period.
Even the tiny tremors from your heartbeat can blur a long-exposure shot of the moon. If you’re using a smartphone, get a cheap tripod adapter. If you’re on a DSLR or mirrorless system, use a remote shutter release or the built-in 2-second timer. This ensures that when the shutter clicks, your hands aren't anywhere near the camera to shake it.
Lenses and Focal Lengths
For those crisp, "fill-the-frame" photos of the blood moon, you generally want something at or above 300mm. A 200mm lens is okay, but you'll end up cropping the image significantly, which eats away at your resolution. If you have a 600mm setup, you're in the big leagues.
But don't ignore wide-angle shots.
Some of the most compelling lunar photography isn't a close-up of craters. It’s the moon hanging over a city skyline, a mountain range, or a lonely lighthouse. This is what photographers call "contextual astrophotography." It tells a story. It proves you were there.
The Smartphone Struggle is Real
Let’s be real: most people are going to use their iPhones or Pixels. If that’s you, stop using the digital zoom immediately. It’s just "fake" pixels created by an algorithm.

Instead, use a dedicated night photography app like Halide or ProCam. These allow you to lock the focus to "infinity" and manually drag the exposure slider down. You want the moon to look slightly too dark on your screen. You can always pull the shadows out later in an editing app like Lightroom, but once you "blow out" the highlights and the moon turns white, that data is gone forever. You can't edit detail back into a white circle.
Another pro tip for mobile users? Use a telescope eyepiece. If you have a pair of binoculars or a basic backyard telescope, hold your phone lens up to the eyepiece. It's called "afocal photography." It’s finicky, and you’ll feel a bit ridiculous trying to line it up, but it can produce surprisingly sharp results that look way better than any 100x digital "Space Zoom."
Atmospheric Conditions: The Silent Killer
You can have a $10,000 setup and still get terrible photos of the blood moon if the atmosphere isn't cooperating. This is what astronomers call "seeing."
If the air is turbulent—due to heat rising off a parking lot or a jet stream overhead—the moon will look like it's underwater. It shimmers and blurs. For the best shots, you want to get away from "thermal mass." Grass is better than pavement. Higher elevation is better than a valley.
And then there's light pollution. While you can see a blood moon from a city, the contrast is much better in "Dark Sky" areas. Use a tool like the Light Pollution Map to find a spot where the sky actually looks black, not hazy purple. The deeper the darkness, the more the red moon will "pop" against the stars.
Editing Without Overdoing It
Post-processing is where the magic happens, but it’s also where people ruin their work. The temptation is to crank the saturation until the moon looks like a glowing maraschino cherry. Don't do that.

The goal of editing photos of the blood moon should be to replicate what the human eye saw. Start with your White Balance. If it’s set to "Auto," the camera might try to "fix" the red and turn it a weird muddy brown. Set your white balance to "Daylight" (around 5500K). This preserves the natural warmth of the eclipse.
Next, look at your "Dehaze" or "Clarity" sliders. A little goes a long way. You want to bring out the definition of the Tycho crater and the radiating rays across the lunar surface without making it look crunchy or artificial.
How to Prepare for the Next One
Eclipses aren't a surprise. They are mathematically predictable. Use an app like PhotoPills or The Photographer’s Ephemeris. These apps allow you to see exactly where the moon will rise and its path across the sky relative to your specific location.
If you want the moon to appear behind a specific building, these apps will tell you exactly where to stand and at what time. It’s the difference between a "lucky" snap and a planned masterpiece.
- Check the weather 48 hours in advance. Clouds are the only thing that can truly cancel the show.
- Scout your location during the day. Find a spot with a clear view of the eastern or western horizon, depending on when the eclipse occurs.
- Bring extra batteries. Long exposures and cold night air drain batteries significantly faster than usual.
- Shoot in RAW. If your camera or phone supports it, always choose RAW over JPEG. It keeps all the data from the sensor, giving you much more room to fix exposure mistakes later.
The best photos of the blood moon are the ones that capture the mood of the event. It’s quiet, it’s slow, and it’s a bit eerie. Whether you are using a high-end mirrorless rig or just a three-year-old smartphone, the key is patience. The eclipse lasts for hours. Don't rush. Experiment with different settings, take a breath, and remember to look up with your own eyes, too. No photo will ever quite match the feeling of seeing the world’s shadow swallow the moon in real-time.
